eurephiadb init: Only setup the requiered function pointers in driver

This is ment as a security enhancement.  Do not setup the function
pointers to functions which is not needed for the requested minimum
driver API version.  Calling any of these functions which is not
set up would then cause a SEGV.

In real life, this means that the eurephia-auth.so which only needs
API version 1 now will not setup any pointers to the API version 2,
which the eurephiadm utility needs.

In the future it should be a 4th argument to the eDBlink_init(...),
defining features to enable when loading the drivers.  This should
be a bitwise mask.  So that API version can change whenever the
driver includes more functions.  But for now, this change is enough.
